Specification of Letters Patent.

Patented Nov. 28, 1911.

Application filed April 1, 1908, Serial No. 424,564. Renewed October 27,1911. Serial No. 657,186.

To all whom it may concern:

Be it known that we, JOHN SGHRUT'H,

ALBERT SOHRUTH, EDWARD SOHRUTH, and WILLIAM ENGE-L, citizens of theUnited States of America, and residents of Pepin, in the county of Pepinand State of Wiscon sin, have invented certain new and usefulImprovements in Bob-Sleds, of which the following is a specification.

This invention relates to new and useful improvements in bob sleds andit is an object of this invention to provide a device of this characterwhich will be an easy goer.

It is also an object of the invention to provide a novel device of thischaracter whereining at the same time comparatively ineX- pensive tomanufacture.

WVith the foregoing and other objects in view, the invention consists inthe details of construction and in the arrangement andcombination ofparts to behereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part of this specification wherein likecharacters denote correspond ing parts in the several views, in whichFigure l, is a fragmentary view in perspective of the invention, thenon-essential features being omitted and the body being indicated indotted lines; and Figs. 2, 3, 4, 5, and 6, are views in perspectiveillustrating various details of the invention. In the drawings A,denotes the front sled of the bob and B, the rear sled. Both of thesesleds are similar in construction except the caps that hold or connectthe runners and raves which are slightly different. It will thereforebe'understood that with the exception of these caps the description ofone of the sleds will be applicable to the arranged on an incline, theends of the stems being secured to the runner 1, while the base portionof the brace supports the rave. To the under surface of the runner issecured the ordinary shoe 4. Resting on the rave 2, above the brace 3,is a block 5, and on this block 5, rests a bearing 6. This bearing 6,

and the bloc-k5, are held in position by the bolts 7, which pass throughthe bearing block, rave, and brace 3, said bolts being held in positionby the nuts 8. Positioned above the bearing 6, is a cross strip or beam9, which has secured to its under face the cast plate 10. Depending fromthis cast plate 10, are the series of spaced perforated cars 11 and 12.The ears 12, bearing 6, and the perforations of these ears register withthe perforation of the bearing and through the bearing and the earspasses the truss-rod 13. This rod also passes t-hrough'the ears 12,before 'refererd to.

The plate 10, may be secured to the beam in any desired manner,preferably by screws passing through the perforations 14, in the basethereof. This plate may be of any destraddle the sired form, but it hasbeen found best that the same be provided with longitudinal side flanges15,.and an end flange 16. The flange 16, is intended to bear against theend of the beam while the flanges 15, contact with the sides of thebeam. This structure reduces the strain on the securing screws to aminimum and holds the plate against any possible, movement on the beam,more espe cially the end flange 16, as under ordinary circumstances theplate has a tendency, owing to the strain thereon, to move inwardly onthe beam.

Positioned between the ears 11, is a knuckle 17, which has alongitudinal opening or bore 18, through which the truss-rod 13, passes,it being understood of course that this knuckle is positioned betweenthe ears before the truss-rod is applied. Beneath the bore 18, adjacentone end thereof, the knuckle is provided with a-transverse bore 19. Thisbore is at the inner end of the knuckle when in applied position and isarranged on an incline toward the runner. Passing through this bore 19,is a brace rod 20, which is secured to the rave 2, adjacent its forwardend. The opposite end of the brace rod 20, is threaded and this threadedportion is engaged by the nut 21, which bears against the knuckle 17. Byturning this nut 21, the tension of the brace rod may be regulated asthe requirements of practice may necessitate. The opposite end of theknuckle 17, is provided with the inwardly converging transverse bore 22,through which passes the brace strip 23. This brace strip 23, is formedof a continuous piece and has its ends secured to the stems of the brace3, hereinbefore referred to. This attachment of the brace 23, to thebrace 3, is preferably effected by having the free ends of the brace 23,terminating in eyes 24, through which pass the headed bolts 25, engagedby the nuts 26, as is thought to be fully shown in Fig. 1.

To the cross beams 9, the body of the bob is secured. By the structureset forth a bob sleigh is provided wherein the supporting sleds aremovable with relation to the body. This arrangement provides a bobsleigh which rides very easily in View of the fact that each sled ismovable independently of the other and of the body, the advantages ofwhich are believed to be apparent without the necessity of anenumeration thereof.

The forward end of the front sled is slightly higher than the front ofthe rear sled, in fact the forward end of the front sled is elevatedslightly above the body. The rave 2, and runners 1, are connected by thecap 27. This cap snugly engages the top and side of the rave and thebottom and side of the runner and is held thereto by the bolts 28. Thetop of the cap has upstanding perforated spaced lugs 28, between whichfits a bearing 29, secured to bar 30, and is pivotally secured to thecap by the bolt 31, which passes through the lugs 28, and the bearing29.

The raves and runners of the sleds B, are each connected by the cap 32,which snugly engages the same and is securely fastened thereto. This cap32, has its point provided with a perforation 33, through which passes astrap 34. This strap 34, is secured to the under surface of the body asshown in Fig. 1. This is done in order that the downward movement of therear sled can be controlled or limited as in practice it has been foundthat the same freedom of movement should not be permitted the rear sledas is permitted the front sled.

We claim:

In a sled, the combination with runners, raves connected to the runners,and means supporting said raves on said runners, of a truss rodextending from one rave to the opposite rave, transversely extendingplates pivotally mounted on said truss rod, said plates having dependinglugs through which said truss rod passes, knuckles on said truss rod,disposed between said depending lugs, each of said knuckles having twolugs, brace members looped through one of said lugs and connected tosaid means supporting said raves, and brace members passing through theother lugs on said knuckles and connected to the forward parts of saidraves, said last mentioned brace members being adjustable with respectto length, whereby the wear upon the pivotal connections between saidraves and said plates may be taken up.

In testimony whereof we affix our signatures in the presence of twowitnesses this 7th day of December, 1907.
